A new range of diffraction grating mounts with a large clear aperture also combine independent and precision rotational adjustment of square components in all three axes – an industry first from Siskiyou Corp.
Siskiyou GMx series mounts can hold 12½ mm, 25 mm and 50 mm square reflective or transmissive optics of any thickness greater than 2 mm, and offer up to 8° of total rotation in each axis, with a resolution as low as 3.2 arcseconds.
All adjustments are accessed from the top of the mount to enable use in space restricted environments, and they can be either table or post mounted for maximum flexibility.
A typical application for GMx mounts would be in the construction of the stretchers and compressors used to manipulate chirped ultrafast laser pulses in laboratory setups, or as OEM components in instruments such as monochromators and spectrometers.
An efficient monochromator utilising the high-brightness Energetiq EQ-99X LDLS™ Laser Driven Light Source (right) has been developed by Mountain Photonics, and was recently demonstrated on our booth at Photonics West.
The Hyperchromator uses an off-axis parabolic mirror to focus the broadband light generated by the small plasma spot of the LDLS™ directly onto a diffraction grating, and then off a second mirror to an exit port.
As no entrance slit is used, the optical efficiency of the system is very high – typically f/1.5 or f/2, depending on the required resolution or throughput. A white light bypass output is also available.
The output port has been designed to allow for a multitude of illumination or light coupling options. By using standard catalogue components, the Hyperchromator can be easily integrated into an application.
The Hyperchromator is controlled via USB/RS-232 and an intuitive GUI, with LabVIEW™ and other software libraries supported.
Existing owners of an Energetiq EQ-99X LDLS™ can add tuneability by purchasing the Hyperchromator unit alone.

The NuSENSOR™ product line, by Nufern, features graded index multimode (MM) fibres designed for Distributed Temperature Sensing (DTS); and single-mode (SM) fibres designed for Distributed Temperature and Strain Sensing (DTSS), and Fiber Bragg Grating (FBG) based sensors.
Both the MM and SM fibres are available with either pure silica or germanium doped core glass compositions, and Nufern is now offering these fibres with carbon/polyimide or carbon/mid-temperature acrylate coatings in addition to the existing polyimide coated fibres. Depending on coating chosen, the fibre is can be protected from temperatures up to 300 °C and H2 rich environments.
